For a while now, 3D printing has been changing the way surgeries are done, bridges are built and artificial limbs are made.

Yet, not everyone has the tech know-how or the budget to invest in a 3D printer set-up.

For the hobbyist who just wants to try their hand at 3D printing, 3D printing pens allow a hands-on way to create 3D objects with technology that fits right at the palm of your hand and even draw in mid-air.

According to Techworm, “The 3Doodler 2.0 pen allows its users to draw in the air by using headed plastic filament that cools instantly into a solid structure. The innovative pen can complete with 125 strands of plastic in 25 colors.”

The reviewer also notes, “The most excellent thing about this pen is that you can also customize the speed of the fan.”

Requiring no software and costing less than $150 for the pen and start-up supplies, the 3Doodler is also a perfect way to introduce 3D printing to kids, hobbyists and anyone who want to give 3D building a try.
